Abstract

A method for describing and comparing data center physical and logical topologies and device configurations. The present invention compares a stored expected network infrastructure description with a current network infrastructure description gathered through the use of monitoring agents. The infrastructure descriptions are compared to discover any differences between the expected infrastructure and the current infrastructure. Devices in the current infrastructure which are configured differently, added, or missing from the expected infrastructure description are listed as well as changes to the logical topology of the current network. The present invention facilitates monitoring the network infrastructure and detecting unauthorized changes or access to the network.

Claims

1. A method for managing a network infrastructure comprising:

storing an expected network infrastructure description;

comparing said expected network infrastructure description with a current network infrastructure description; and

outputting a result of said comparing step, wherein differences between said expected network infrastructure description and said current network infrastructure description are displayed.

2. The method for managing a network infrastructure as recited in claim 1, wherein said network infrastructure is a switched network infrastructure.

3. The method for managing a network infrastructure as recited in claim 1, wherein said method further comprises changing said network infrastructure with a configuration agent and storing said change in said expected network infrastructure description.

4. The method for managing a network infrastructure as recited in claim 1, wherein said comparing further comprises collecting said current network infrastructure description.

5. The method for managing a network infrastructure as recited in claim 4, wherein said collecting of said current network infrastructure description further comprises using agents to collect said current network infrastructure description.

6. The method for managing a network infrastructure as recited in claim 1, wherein said comparing further comprises converting said expected network infrastructure description into an expected network infrastructure graphical description and converting said current network infrastructure description into a current network infrastructure graphical description.

7. The method for managing a network infrastructure as recited in claim 6, wherein said comparing further comprises comparing said expected network infrastructure graphical description with said current network infrastructure graphical description.

8. The method for managing a network infrastructure as recited in claim 1, wherein said outputting further comprises:

outputting a list of devices from said expected network infrastructure description which are missing from said current network infrastructure description;

outputting a list of devices from said current network infrastructure description having a different configuration from the configuration of said devices in said expected network infrastructure description; and

outputting a list of devices from said current network infrastructure description which are not described in said expected network infrastructure description.

9. The method for managing a network infrastructure as recited in claim 1, wherein said outputting further comprises:

outputting a message stating that said expected network infrastructure description and said current network infrastructure description are identical.

10. A computer system comprising:

a bus;

a memory unit coupled to said bus; and

a processor coupled to said bus, said processor for executing a method for managing a network infrastructure comprising;

storing an expected network infrastructure description;

comparing said expected network infrastructure description with a current network infrastructure description; and

outputting a result of said comparing step, wherein differences between said expected network infrastructure description and said current network infrastructure description are displayed.

11. The computer system as recited in claim 10, wherein said network infrastructure is a switched network infrastructure.

12. The computer system as recited in claim 10, wherein said method further comprises changing said network infrastructure with a configuration agent and storing said change in said expected network infrastructure description.

13. The computer system as recited in claim 10, wherein said comparing further comprises collecting said current network infrastructure description.

14. The computer system as recited in claim 13, wherein said collecting of said current network infrastructure description further comprises using agents to collect said current network infrastructure description.

15. The computer system as recited in claim 10, wherein said comparing further comprises converting said expected network infrastructure description into an expected network infrastructure graphical description and converting said current network infrastructure description into a current network infrastructure graphical description.

16. The computer system as recited in claim 15, wherein said comparing further comprises comparing said expected network infrastructure graphical description with said current network infrastructure graphical description.

17. The computer system as recited in claim 10, wherein said outputting further comprises:

outputting a list of devices from said expected network infrastructure description which are missing from said current network infrastructure description;

outputting a list of devices from said current network infrastructure description having a different configuration from the configuration of said devices in said expected network infrastructure description; and

outputting a list of devices from said current network infrastructure description which are not described in said expected network infrastructure description.

18. The computer system as recited in claim 10, wherein said outputting further comprises:

outputting a message stating that said expected network infrastructure description and said current network infrastructure description are identical.

19. A computer-usable medium having computer-readable program code embodied therein for causing a computer system to perform a method for managing a network infrastructure comprising:

storing an expected network infrastructure description;

comparing said expected network infrastructure description with a current network infrastructure description; and

outputting a result of said comparing step, wherein differences between said expected network infrastructure description and said current network infrastructure description are displayed.

20. The computer-usable medium as recited in claim 19, wherein said network infrastructure is a switched network infrastructure.

21. The computer-usable medium as recited in claim 19, wherein said method further comprises changing said network infrastructure with a configuration agent and storing said change in said expected network infrastructure description.
